[Series 65] 43, Efficient Market Hypothesis

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Weak-form EMH states that past price and volume data are priced in, making technical analysis ineffective. - Semi-strong form EMH posits all public information is reflected in prices, rendering both technical and fundamental analysis useless for outperformance. - Strong-form EMH asserts that all information, including private insider data, is priced in, making it impossible for anyone to consistently beat the market. - A strong belief in the Efficient Market Hypothesis logically leads to a preference for passive investment strategies, like index funds, over active management. - The Random Walk Theory aligns with EMH, suggesting stock price changes are random and unpredictable, reinforcing the idea that past performance cannot predict future results.
